The Willem River or Willem's River was named during the voyage of the Dutch East India Company ship Mauritius in 1618, under the command of Supercargo Willem Janszoon and captained by Lenaert Jacobszoon, and is one of the few features named on a nautical chart made in 1627. [1]
It seems reasonable that Willem River was almost certainly named after Supercargo Willem Janszoon, the Commander of the ship Mauritius. Janszoon was captain of the Duyfken in 1605–1606, when part of the Gulf of Carpentaria was mapped, during the earliest documented visit to Australia by a vessel from Europe. [1]
Caert van't Landt van d'Eendracht ("Chart of the Land of Eendracht") is a 1627 chart made by Hessel Gerritsz and is one of the earliest charts showing the coastline of Western Australia. [1] The Willem River is located to the extreme left (north) end of the coastline on the chart and a closer view is provided below.
It is believed that the Willem River of 1618 is the Ashburton River in Western Australia. [2] The chart shows Willems revier, besocht by 't volck van 't Schip Mauritius in Iulius A° 1618 (translated Willem's River, visited by the crew of the ship Mauritius in July 1618).
The detail of the river's position on the chart backs up the claim that this is the Ashburton River, which, being at 21 degrees 40 minutes south and 114 degrees 56 east, is almost exactly the latitude shown on the chart. The chart is oriented with north to the left, showing lines of latitude from 20th parallel south to the 35th parallel south at the base of the map. The lines of latitude appear to be very accurate, matching closely known features through the length of the chart.
Other factors to back up that this is the Ashburton River is that it takes almost a 90 degree turn north-east once in the mouth as shown on the chart, and the northern headland of the river mouth in reality is of the same shape as shown on the chart. However, significant changes to the river delta since 1963 alone have been observed. These changes include channel and mouth movements, and erosion and formation of spits. [3] [4] [5] [6] For example, between 1973 and 2008 the eastern spit at Entrance Point migrated eastwards by approximately 2.2 kilometres (1.4 mi). [6]
A note on the chart's accuracy is given by the author Heeres in 1899, from the following excerpt.
The 1627 chart is specially interesting. Gerritsz., at the time cartographer in ordinary to the E.I.C., has "put together this chart of the Landt van d'Eendracht from the journals and drawings of the Steersmen", which means that he availed himself of authentic data [***]. He acquitted himself of the task to admiration, and has given a very lucid survey of the (accidental) discoveries made by the Dutch on the west-coast of Australia. In this chart of 1627 the Land of d'Eendracht takes up a good deal of space. To the north it is found bounded by the "Willemsrivier", discovered in July 1618 by the ship Mauritius, commanded by Willem Janszoon [****]. According to the chart this "river" is in about 21° 45' S. Lat., but there are no reliable data concerning this point.
[*** It is evident that he did not use all the data then available. Thus, for instance, he left unused those furnished by the Zeewolf (No. VIII, pp. 10 ff. below), and those of the ship Leiden (No. XV, p. 49).]
[**** See the Documents under No IX (pp. 12f.).] [1]
What Heeres means by the sentence, According to the chart this "river" is in about 21° 45' S. Lat., but there are no reliable data concerning this point, is that in 1899 they had no reliable information about exactly what was at that latitude.
On 31 July 1618, the Mauritius reached North West Cape (west of Exmouth Gulf), where crew members went ashore and saw footprints; [1] this was the closest that Europeans had yet come to making contact with indigenous Australians in Western Australia.
Janszoon and Jacobszoon assumed that the cape was an island: the notion later took hold amongst mariners and cartographers, to the extent that it was named "Cloates Island" in 1720 and this misconception lingered until the 19th century.
As Willem's River was also named in July it would appear that the Mauritius, which reached Bantam, Indonesia on 22 August 1618, discovered the river on the same day that they reached North West Cape (that is, 31 July 1618, the last day of July). [1]
The 1627 chart was based on a number of voyages, beginning with the 1616 voyage of Dirk Hartog. On that voyage Hartog named Eendrachtsland after his ship, the Eendracht meaning "Unity". [1] Eendrachtsland is one of the earliest names given to the Australian mainland. [1]
Abel Janszoon Tasman was a Dutch seafarer, explorer, and merchant, best known for his voyages of 1642 and 1644 in the service of the Dutch East India Company (VOC). He was the first known European explorer to reach New Zealand and the islands of Fiji and Van Diemen's Land.
The maritime European exploration of Australia consisted of several waves of European seafarers who sailed the edges of the Australian continent. Dutch navigators were the first Europeans known to have explored and mapped the Australian coastline. The first documented encounter was that of Dutch navigator Willem Janszoon, in 1606. Dutch seafarers also visited the west and north coasts of the continent, as did French explorers.
Dirk Hartog was a 17th-century Dutch sailor and explorer. Dirk Hartog's expedition was the second European group to land in Australia and the first to leave behind an artefact to record his visit, the Hartog Plate. His name is sometimes alternatively spelled Dirck Hartog or Dierick Hartochszch. Ernest Giles referred to him as Theodoric Hartog. The Western Australian island Dirk Hartog Island is named after Hartog.
Willem Janszoon, sometimes abbreviated to Willem Jansz., was a Dutch navigator and colonial governor. Janszoon served in the Dutch East Indies in the periods 1603–1611 and 1612–1616, including as governor of Fort Henricus on the island of Solor. He is the first European known to have seen the coast of Australia during his voyage of 1605–1606.
Cape Leeuwin is the most south-westerly mainland point of the Australian continent, in the state of Western Australia.
The Eendracht was an early 17th Century Dutch wooden-hulled 700 tonne East Indiaman, launched in 1615 in the service of the Dutch East India Company (VOC). Its Dutch name means "concord", "unity" or "union", and was a common name given to Dutch ships of the period, from the motto of the Republic: Concordia res parvae crescunt. The ship was captained by Dirk Hartog when he made the second recorded landfall by a European on Australian soil, in 1616.
The Ashburton River is located within the Pilbara region of Western Australia.
The Pennefather River is a river located on the western Cape York Peninsula in Far North Queensland, Australia.
Eendrachtsland or Eendraghtsland was derived from 't Landt van d'Eendracht or Land van de Eendracht and was one of the earliest names given by Europeans to Australia, being in use for 28 years, from 1616 until 1644.
North West Cape is a peninsula in the north-west of Western Australia. Cape Range runs down the spine of the peninsula and Ningaloo Reef runs along the western edge. It is in the Gascoyne region and includes the town of Exmouth.
Lenaert Jacobszoon was a captain of the Dutch East India Company who, on 31 July 1618 in the vessel Mauritius, sighted North West Cape in the north-west of Western Australia mistakenly believing it to be a large island. He also named the Willems River and the Jocob Remmessens River in the same voyage.
Point Cloates, formerly known as Cloate's Island, is a peninsula approximately 100 kilometres south south-west of North West Cape, in the Pilbara region of Western Australia. It features Point Cloates Lighthouse and the ruins of a previous lighthouse ; both buildings are on Cloates Hill, which rises 41 metres above sea level.
Willem Janszoon captained the first recorded European landing on the Australian continent in 1606, sailing from Bantam, Java, in the Duyfken. As an employee of the Dutch East India Company, Janszoon had been instructed to explore the coast of New Guinea in search of economic opportunities. He had originally arrived in the Dutch East Indies from the Netherlands in 1598, and became an officer of the VOC on its establishment in 1602.
Hessel Gerritsz was a Dutch engraver, cartographer, and publisher. He was one of the notable figures in the Golden Age of Netherlandish cartography. Despite strong competition, he is considered by some "unquestionably the chief Dutch cartographer of the 17th century".
Leeuwin, was a Dutch galleon that discovered and mapped some of the southwest corner of Australia in March 1622. It was the seventh European ship to sight the continent.
Caert van't Landt van d'Eendracht is a 1627 map by Hessel Gerritsz. One of the earliest maps of Australia, it shows what little was then known of the west coast, based on a number of voyages beginning with the 1616 voyage of Dirk Hartog, when he named Eendrachtsland after his ship.
Thirteen ships of the Dutch East India Company and its pre-companies have been named Amsterdam.
Pieter Schouten was a 17th-century Dutch corsair and privateer. He was one of the first Dutchmen to explore to the Caribbean and, while employed by the Dutch West Indies Company, was involved in extensive reconnaissance to establish Dutch bases in the West Indies.
Of an estimated 200 place names the Dutch bestowed on Australian localities in the 17th century as a result of the Dutch voyages of exploration along the western, northern and southern Australian coasts, only about 35 can still be found on current maps. Five out of six names were either renamed or forgotten or their locations were lost. Other places were named after the early Dutch explorers by later British explorers or colonists, for instance the Australian state of Tasmania is named after Abel Tasman. Australia itself was called New Holland by the English and Nieuw Holland by the Dutch.
The Mauritius was an early 17th Century Dutch wooden-hulled sailing ship, documented as being in service to the Dutch East India Company between 1618 and 1622.
